Patented May 27, 1952 UNITED STATES PATENT OFFME MATERIAL Charles E.Marks, Lee, Mass, assignor to General Electric Company, a corporation ofNew York Application September 1, 1948, Serial No. 47,246 7 Claims. (01.154-115) The present invention relates to a method and apparatus forattaching a plurality of strips of material, at spaced and equalintervals, to another strip of material. More particularly, my inventionrelates to an improvement over the method and apparatus for transverselyafiixing a plurality of conducting tap straps to a wider strip ofinsulating mounting material disclosed in the copending applications ofRaney, Serial No. 41,804, filed July 31, 1948, Serial No. 116,346, filedSeptember 17, 1949, and the copending application of Hogue & Hamilton,Serial No. 46,206, filed August 26, 1948, now Patent No. 2,597,863, eachassigned to the same assignee as the instant application. The broadaspects of any features disclosed in these copending applications andcommon to the instant application are to be regarded as prior art withrespect to this present application which is directed to a particularand distinguishing combination of elements not disclosed in these priorart applications. The claims of the present application are specificallydirected to the apparatus of the present invention while claims to themethod have been presented in my copending, divisional application,Serial Number 116,316, filed September 17, 1949, and assigned to thesame assignee as the present application, now Patent No. 2,597,885.

It was indicated in aforementioned application Serial N 0. 46,206 thatin order to employ the combination of a plurality of conducting tapstraps afiixed to a longitudinal strip ofv insulating mounting materialin the manner disclosed in copending application Serial No. 18,104,filed March 31, 1948, now Patent No. 2,547,644, the longitudinal stripof insulating paper must have the conducting tap straps afiixed theretonot only at spaced and equal intervals but a portion of each tap strapmust extend a predetermined distance, laterally beyond a longitudinaledge of the mounting strip, approximately equal to the distance it isdesired to have the tap strap project out of the finished condenserroll. The desirability and reasons for having the projecting portion ofeach tap strap free of any contamination, such as adhesive materialemployed to adhere the strap to the mounting strip, was also pointedout.

I In addition to the fulfillment of these requirements, however, it isalso desirable to carry out the operation of afiixing tap straps andcompleting a great number of finished rolls in a minimum of time.Reduction in the time required to assemble a finished roll obviouslywould be realized if the necessity of momentarily stopping the movementof the mounting strip could be eliminated while each tap strap is beingaffixed thereto. However, aside from the problem involved in therealization of this objective, an additional problem is presented inthat it would be difiicult, practically, if not impossible, to applyadhesive material to a mounting strip while in motion.

It is, therefore, an object of my invention to provide an improvedmethod for affixing, at spaced and equal intervals, a plurality ofconducting tap straps to a mounting strip of insulating material.

It is also an object of my invention to provide a method for afl'ixingsuch tap straps While the mounting strip is in motion.

It is a further object of my invention to provide a method of afiixingconducting tap straps to a mounting strip whereby adhesive material isapplied to only such surfaces of the tap strap or mounting strip as willbe in engagement after afiixing to each other.

It is still a further object of my invention to provide a new andimproved apparatus for automatically carrying out the method described.

My invention will be better understood from the following descriptionwhen taken in connection with the accompanying drawings and the scope ofmy invention will be pointed out in the appended claims.

In the drawings, Fig. 1 is a perspective and diagrammatic representationof an apparatus embodying my invention; Fig. 1a is an enlarged edge viewof an adhesive applicator element incorporated in the Fig. 1 apparatus;Fig. 2 is a perspective and diagrammatic illustration of a similarapparatus incorporating a modification of my invention and Fig. 2a is anenlarged edge view of the adhesive applicator element incorporated inthe Fig. 2 apparatus.

Referring now to Fig.1 of the drawings, It represents a supply roll ofinsulating mounting material rotatably mounted on spindle or shaft IIwhich in turn is supported by a stationary frame work not illustrated inthe interest of simplicity. As supply roll 10 is unwound, by drive meansto be described hereinafter, the longitudinal strip of mounting material12 therefrom is directed toward the left in the direction of the arrowand during this leftward passage passes over and is temporarilysupported on supportv fed from a supply roll or reel, not shown, in thedirection of the arrow toward and transversely over the platform l3 andthe longitudinal supply strip of mounting material I2. To feed theconducting strip l4 transversely toward the mounting strip I employ feedmeans comprising a pair of cooperating feed rolls I5 and I6 fixedlymounted on shafts l1 and I8 respectively which are positivelyinterconnected by spur gears I9 and respectively. Shaft I1 is drivenclockwise, as viewed, by bevel gear set 2 I, shaft 22, bevel gear set 23and shaft 24 from a pulley or chain sprocket mounted thereon but notshown which in turn may be driven by a belt or chain from a motorneither of which are illustrated. Notches I5 and I6 have beenrespectively cut across the con- Q tacting periphery of rolls I5 and I6which are so mounted on their respective shafts that during eachrevolution thereof notches I5 and It are bisected by a lineinterconnecting the centers of the rolls or are adjacently disposed onopposite sides of the conducting strip I4 therebetween. Since theperiphery of the rolls are out of engagement with the strip at thistimethe feed thereof is obviously terminated for a momentary period duringeach revolution of the feed rolls. A pair of cooperating rotatable discs25 and 26 between which conducting strip I4 is directed while being fedby the feed rolls toward platform I3 is positioned between feed rolls I5and I6 and the platform. Discs 25 and 26 are fixedly mounted on andpositively driven by shafts 21 and 28 respectively through spur gears 29and 30 by idler gear 3| which meshes with gear I9 fixed to feed rollshaft I1. These discs are 'so positioned on their respective shafts withrespect to each other and strip I4 is so directed therebetween that thelongitudinal axis thereof is aligned with the central plane of rotationof each disc. Although disc 25 is a complete circular disc, disc 26comprises substantially the sector of a circle with I portion of disc 26engages the under surface of conducting strip I4 so that for a shortperiod each revolution of the discs, disc 26 is completely out ofengagement with the conducting strip It as it is fed between the discs.It should be observed at this point that disc sector 26, as betterillustrated in Fig. 1a, has a thickness less than the width ofconducting strip I4 and the circular periphery portion thereof rotatesin a bath of adhesive material 32 in supply reservoir 33 which isprovided with any suitable heating means to maintain the adhesivematerial therein in a liquid state.

Between feed rolls I5 and I3 and discs 25 and 26 at a predetermineddistance from platform l3 and the adjacentlongitudinal edge of mountingstrip [2 is supported a conducting strip severing means or knifesubstantially the same as the severing means disclosed in the abovementioned copending application of Hogue and Hamilton, Serial No.46,206. This severing means comprises a die and strip support 34 rigidlyfixed to the apparatus frame work and punch or knife housing 35 slidablymounted for vertical movement at the rear, but not shown, on the framework. The forward lower end 35 of housing 35 is'formed or machined toaknife edge, the purpose of which will be apparent as the descriptionproceeds. Conducting strip holding element 36 is mounted'for verticalmovement'within housing 35, biased downward by a'spri n'g therein andaligned for engagement with die slot 31 which has a width and is soaligned as to slidably accommodate conducting strip I4 as it is fedtoward mounting strip I2. The downward travel of holding element 36under its spring bias is limited by the engagement of a pin 38 affixedthereto with the lower edge of a slot39 in the side wall of knifehousing 35. Normally, holding element 33 is biased out of engagementwith die slot 31 by springs 40 interposed between top plate 4!,

fixed to housing 35, and the slotted flange 42 of a substantiallychannel shaped backing member 33 fixedly mounted on the frame work.Upward thrust of springs Ml is resisted by engagement of a bolt 44,passing through plate 4| into housing 35, with the rounded end of anadjustment screw 25 threadably mounted in a beam or lever 45 rotativelypivoted on pivot pin 41 fixedly mounted on the apparatus frame work. Camwheel 38 is rotatively mounted at one end of lever 55 and is "biasedinto engagement with cam 39 mounted on an extension of drive shaft 24 byspring interposed between lever 46,-at the other end thereof oppositethe pivot pin 41, and flange 5i of channel shaped backing member 43. Anextension 52 is provided at this end of lever it to which one arm 53 ofa toggle is pivotally mounted at pivot pins 54. A toggle tamper 55having a length approximately equal to the width of the mounting strip-I2and a rounded tamping surface is pivotally mounted transversely withrespect to the mounting strip to the lower end of arm 53 by means ofpivot pin 55. This combination comprising atoggle is biased in acounterclockwise direction by'spring 51, attached to arm 53 and adownwardly projerting portion of lever extension 52. However, stop 53,part of the downwardly projecting portion, normally preventscounterclockwise movement of the toggle tamper beyond the positionindicated which is such'that the longitudinal center line of the tampingsurface on tamper 55 is aligned with the longitudinal axis of theconducting strip I4 fed over the mounting strip l2. Moreover, arm 53 isso mounted with respect to platform I3 and mounting strip I 2 that itsmovement about pivot 54 is in a plane normal to the platform surface andcoincident with a horizontal center line thereof and the longitudinalaxis of the mounting strip.

So as to prevent back-lash of conducting strip it, a pairof frictionblocks 59 are provided between which thestrip is pulled by feed rolls I5and It. The lower friction block is supported on the stationary framework while the upper block is movable but biased downwardly by spring 60interposed therebetween and a part of the frame work 6!.

A friction drive roll 62 is fixedly mounted on shaft 63 which ispositively connected by spur gear 64 fixed thereto and spur gear 55 todrive shaft 2%. 65 represents a partially wound reel of mountingmaterial with tap straps affixed thereto in substantial rollingengagement withv friction roll 62 and wound on a split mandrel mountedon reel up shaft 6? which is supported on a radius arm, not shown, whichin turn is pivotally mounted on the apparatus frame work, as illustratedin the above mentioned copendingapplication of Hogue and Hamilton. It isby means of friction roll 62 that the mounting strip I2 is unwound fromsupply roll I0 and directed over platform It by idler guide'rolls 58 and69 around friction roll 62 and'eventually rewound into-a-reel-s-uchas65. Them'ountingbfshaft 51 on a pivoted radius arm results in constantrolling engagement of the reel being rewound with friction drive roll 62regardless of the amount of mounting material that has been rewound intoa finished reel. 10 represents an ironer roll rotatably and alsoslidably mounted for vertical movement on the apparatus frame work butbiased downwardly toward the upper surface of platform I3 forrollingengagement with moving mounting strip'I'z.

To operate -.the apparatus hereinbefore described, an end of mountingstrip I 2 is first manually pulled over support platform I3, directedaround guide rolls 68 and 69 and friction drive roll 62 as shown andattached to the split mandrel on shaft 61 and an end of conductingstrip,

I4 is manually directed between friction blocks 59 into frictionalengagement with the circular peripheries of feed rolls I5 and I6. Thenthe drive motor, not shown, which turns drive shaft 24, gear 65 and cam49 in a clockwise direction is started. Thereafter all the steps of myinvention are executed automatically. Drive feed'roll 62 unwinds thelongitudinal mounting strip I2 from supply roll I continuously acrosssupport platform I3 around the guide rolls and rewinds it intothe reel66. Feed rolls I and I6 feed the conducting supply strip through the dieslot 31 toward and transversely over continuously moving mounting stripI2 for a lineal distance equal to the circumferential dimension of thecontacting periphery of a feed roll.

Simultaneously during the feed, the circular periphery portion of disc26 which has previously rotated in the liquid adhesive material 32engages the bottom surface of conducting strip I4 to apply a strip ofadhesive thereto having a lineal dimension equal to the circumferentialdimension of the engaging periphery of the disc. Because of the locationof disc 26 with respect to the adjacent longitudinal edge of movingmounting strip I2, the angle subtending the circular periphery of disc26 and the synchronization thereof With'the feed rolls, this strip ofadhesive is applied only to that portion of strip I4 which is adjacentto and fed over mounting strip I2. Moreover, since disc 26 has athickness less than the width of strip I4 and because the longitudinalaxis thereof is aligned with the central plane of rotation of disc 26,the adhesive material which is applied is confined to a very narrowstrip about the longitudinal center line of the bottom surface of theconducting strip.

Thereafter, notches I5 and I6 of feed rolls l5 and I6 respectivelybecome adjacently disposed at which time the feed of strip I4 ismomentarily stopped. The various elements of the apparatus areinterconnected as hereinbefore described and so synchronized that duringthis momentary period the detented or depressed portion 1| inthecontacting surface of rotating cam 49 begins to roll into engagementwith cam wheel 48 permitting biasing spring 50 to turn lever or beam 46clockwise about its fulcrum or pivot 41 thereby depressing housing 35downwardly, against the biasing action of springs 48, and the lower endof holding element 36 into engagement with conducting strip I4 in dieslot 31.

Additional rotation of cam 49 results in further downward and slidablemotion of housing 35 this time relative to holding element 39, whichhaving engaged stationary die slot 31 and strip I4 remains stationary,whereupon the knife edge 35' of housing 35 passes through and seversconducting strip I4. As pointed out in the above indicated 'copendingapplication, by virtue of the resulting compression of the spring withinthe housing, this additional downward movement of housing 35 imposesconsiderable holding pressure on strip I4 during the actual severingthereof. This clockwise motion of the beam 46 also and simultaneouslylowers toggle tamper 55 into rolling and pressure engagement with thatportion of the conducting strip which has previously been fed over themounting strip I2 whereby the adhesive coated undersurface of theconducting strip now severed is pressed into engagement with themounting strip. The severed conducting strip thus adhesively affixed tothe continuously moving mounting strip will promptly move therewith tothe left and because of the friction between the conducting tap strapand the curved lower surface of; the tamper 55 and the pivoted mountingthereof the toggle tamper elements will move a short distance therewithclockwise about pivot pins 56 and 54 against the biasing action ofspring 51 after which disengagement of the detentecl portion H ofrotating cam 49 will result in counterclockwise movement of beam 46about pivot 41 to raise tamper 55 for free counterclockwise movement ofarm 53 about pivot 54 under the biasing action of spring 51 intoengagement with stop 58. This movement of lever 46 simultaneouslypermits upward vertical movement of punch or knife 36 under the biasingaction of springs 46. Spring biased roller 10 serves to applypressure'for an additional short period to the afifixed conducting tapstrap as it passes therebetween and the surface of support platform I3.

Thus, a new and improved method and means has been provided whereby aconducting tap strap 12 having a predetermined portion projecting beyondor exterior a longitudinal edge of a strip of mounting material isautomatically affixed thereto at spaced and equal intervals while themounting strip is in continuous motion. Moreover, in accordance withthis new method and means both surfaces of the projecting portion ofeach tap strap are entirely free of any insulating material such as theadhesive em ployed to bond the tap to the mounting strip. 7

In Fig. 2, I have illustrated an apparatus somewhat similar to the Fig.1 apparatus except that a modification of my invention is embodiedtherein and other features have been incorporated which render thismachine more flexible than the apparatus illustrated in the Fig. 1embodiment. As in the embodiment of Fig. l, a' supply roll of insulatingmounting material is rotatably mounted on a spindle or shaft 8]. Alongitudinal strip of material 82 is unwound therefrom and pulled underidler rolls 83 and 84 across stationary platform 85 and rewound into afinished roll 86, after tap straps have been aflixed thereto, byfriction roll 81. Friction roll 81 is fixedly mounted on shaft 88 whichis con-f tinuously rotated clockwise through bevel gear set 89, shaft90, bevel gear set 9|, drive shaft 92, and drive pulley 93 keyed theretoby a motor through a belt, neither one of which are shown;

A supply strip of conducting material 94 is fed from a supply reel 95through a guide slot 96' toward and transversely over the mounting strip82 and the platform 85 by a pair of cooperative. feed rolls 91 and 98.Feed rolls 91 and 98 are keyed respectively to rotatable shafts 99 andI60 which are positively interconnected by spur gears I8I and I82respectively. driven by a bevel gear I03 keyed to feed roll shaft 99,bevel gear I04 meshing therewith and The feed rolls are,

endrthereof is; hollow to-slidablyreceive; shaft I105which'isrotationallydriven by shaft I09 through thexngaeement ;of.;a-pin fixed on-gshaft I with longitudinal :sl t in the hollow nortion ofshaft I09. The upper endofshaftlflq is mounted for rotationxwithinanadjustment device I I0 havin a thread d portion II I engageable with thethreads ,Of agnut I12 welded or otherwise fixed tothe;,stat ionarjframework I I3 of theapparatus. Since Shafts I and ID!) are axiallymovable with .respectto each other disc H18 may therefore be movedradially toward or away from the peripheryorcenter :of drive disc IIitjby turning threaded portion I I Iwithin nut I I2 whereby therotational speed of: feed rolls 9! and 98. may be varied. The

purpose of such --a variable speed drive is to change the tap straplength when employing different :widths of paper. Driving disc I06,keyed to, shaft- I 01, is rotated constantly by drive shaft 92'throu ghspur gears H4 and H5 keyed respectively to-shafts 92 and I61. Aconducting strip severing means comprising a shear blade H6, positionedbetween thefeed rolls and platform-85 and vertically movable withinstationary bladeguides II'Isuitably fixed to the apparatus framework, isprovided to carry out the'conducting-strip'severing function as in themain embodiment.

A tamper H8 pivotally mounted at [I9 on block I for counterclockwisemovement against the biasingaction of spring I2I is also provided. BlockI20 is removably mounted on a projection I22 integral with or otherwisesuitably fixed to shear blade II6. By means of wing nut I23, block I20,and the tamper may be quicklyremoved and reversibly remounted onprojection I22 so that tamper II8 may swing clockwise vagainst itsspring bias, the purpose of which will be explained hereinafter.

The cutting edge of shear blade H6 is normally biasedawayfrom conductingstrip-94 and to gle -I I8 is biased away from platform '85 by springsvI'24interposed between stationary blade guides III vand-a'yokeorextension I25 fixed-to shearblade H6. .Springs I24 also bias a camroller I26 mounted on crosshead I21, which is in turnflxed to yoke I25,into constant rolling engagement with. cam I28 mounted on shaft I41.

In contrast to'the Fig. .lembodiment feed rolls 91 and v98 .arecompletely circular and-oneend ofshaft I00, to which feed roll 88 iskeyed,is rotatably mounted one pair 'of radiusarms I29 .fixedoto shaftI353 which in turn is pivotally mounted on..t-h e apparatus frame work.Spring I3 I, interposed between one of theradius arms and Ya portion ofthe-stationary framework I32 normally biasesfeed roll 98 toward theconductins strip 94and into cooperation with feedaroll 91. However,afeed r011 pushrod I33 ismounted ationeend'to yoke IZE andthe oppositeor lower end is engageable with one of the radius arms I29 sothatwhenshear blade I I6 is moved downwardly'by cam I28, feed roll 98 is movedout of engagement with strip 94 and away from feed roll 91 against thebias of spring I3I. Although feed ,;roll 98 is positively and constantlydriven, this movement is, nevertheless, permittedby the pin and slotcoupling I34 and universal joint I -35 in Shaft II I10.

was the: case .in .theTFig. 1 embodiment, an

adhesive reservoir I36 containingv liquid adhesive therein is positionedbetween "the :shearing means .and platform .65. An adhesive :applica'tordisc I3! is also provided and mountedqfor rotation of at least a portionthereof :in :the liquidadhesive as better illustrated in Fig. :2a.Unlike the Fig. :1 embodiment, however, disc I 31 is completelycircularand is keyed 'to ashaft I39 which is rotatably mountedcon.arpair .ofrardius arms I4i! fixed to a shaft -I4I :pivotallymountedontthe apparatus framework. Amam roller I142 is;mounted on the:upper endzofga push rod I43,-the opposite or lower'end. of'which isfixedly connected to one of-the radius .sarms I49. A coil spring I44-mounted'around push rod I43 .andinterposed betweenicam roller :I42 andpush rod guide I45, fixed .to :the stationary framework, biases adhesiveapplicator disc .13! into engagement with conducting. strip 94 r androller I42 into engagement with a cam r146 keyed to shaft I531. To allowfor, a. slight.movement of adhesive applicator disc on arms I40 awayfrom conducting strip 94, shaft I39 is driven through a flexible shaftI41 which'is in turn driventhrough gears I48, vI49, and I50 by gear W2keyed to shaft I00.

As to theoperation of the apparatus hereinbefore described, energizationof ,the ;motor which drives shaft 92 will initiatemovement of mountingstrip 82 in the direction of the 'arrow across platform 85 andfeed of anend of conducting strip 94 toward and transversely over the mountingstrip as in the main embodiment. Adhesive applicator disc I3L-during aportion of-this feed willbe in engagement with the underside of theconducting-stripwhereby a narrow strip of adhesive material willbeapplied thereto. While conducting strip 94 is still in motion, cam I46will become effective to depress push rod I43 downwardly against thebias of spring I44 and disc I31 cut of engagement with the conductingstrip. The portion :of the conducting strip thereafter fed toward themounting strip represents that portion of the eventual tap strap whichwill project beyond the edge thereof. Shortly thereafter, cam I28 willbecome effective to start downward movement of shear blade H6 and yokeI25, whereupon further feed of conducting strip 94 will be momentarilystopped since push-rod I33 connected to the yoke will thereby depressradius arms I29 and feed roll 98 mounted thereon out of engagement withconducting strip 94. Upon further downwardmovement of shear blade IIS,the cutting edge thereof will pass through,"there by severing conductingstrip 94. Simultaneously, tamperl I8 will be lowered into rolling andpressure engagement with the severed portion, whereupon the tamper willtravel a short distance therewith counterclockwise about its pivot [I9as was the case in the main embodiment. Then cam I28 will becomeeffective to permit rise of shear'blade II6 under the biasing action ofsprings I24 and simultaneous rise of tamper H3 out of engagement withthe moving tap strap, now firmly anixed to the mounting strip, whereuponthe tamper is free to swing clockwise under the bias of spring I2I toits initial the .moving. mounting strip. .As the shear .blade and yokeI25 approach the uppermostposition of their travel, the raising of pushrod I33 will allow spring [3| to move rotating feed roll 98 intopressure engagement-with conducting strip 94, whereupon the previouslysevered. end thereof will be moved into engagementwith the applicatordisc I3! and then. over the moving mounting strip.

This apparatus, thus embodying a modification of my invention, issomewhat more flexible than the apparatus shown in the Fig. 1 embod mentin that both rolls for use on the righthand side as well as rolls foruse on the lefthand side of the tap strap inserter machine disclosed'i'nthe above mentioned copending application, Serial No. 18,104 may be madeon the same machine. The operation hereinbefore described involved theassembly of a left-hand roll. To assemble tap straps on a right-handroll, a supply roll or reel corresponding to supply roll 80 is mountedon spindle I60 corresponding to spindle 8| after which the mountingstrip is pulled to the left instead of to the right across the platform85 around friction roll Nil, corresponding to friction roll 81 forre-winding into a finished roll on radius arm I62 corresponding toradius arm I53. Before starting the actual assembly of such a right-handroll, tamper support block I20 is removed from support arm I22 andreversibly mounted thereon so that the tamper will be free to moveclockwise with and in the direction of movement of the mounting stripagainst the biasing action of spring I 2|.

While I have, in accordance with the patent statutes, shown anddescribed a particular embodiment of my invention and a modificationthereof including methods of operation together with apparatus forautomatically carrying them out, other changes will be obvious to thoseskilled in the art; and I, therefore, aim in the appended claims tocover all such changes as fall within the true spirit and scope of myinvention.
